I'm pretty new to the tractor world, so please forgive my ignorance. I have a New Holland 914A mower (72") that I'm going to sell. The manual that came with it says "for 1320-1925 tractors". I cannot find any reference to newer models that this will fit. I've been to the NH web site, which doesn't acknowledge they ever made these models. Is there a place (web site) or book which would tell me anything about this? Any help is really appreciated.
